The objeetsofthis invention'are: I

. 1. 'T otsupply' a simple and'iefiicient portable pumping equipment for general pump i ing servicepvhich mayheiattaclied to i H detached fromatractor at will, and Open ated from apower take-OE with which such tractor is supplied for the operationiof extraneous niach-inery 2. To supply a.) pumping of such nature and construction, thatiitj may be attached to l and 'detachdfroni atractor; with sufficient facility as, to render suitable for fire fighting service,in such localities and eiriplo'yed r, v I I 3: To supply" an efficient and comparaclasses of service, as -tractors aregenerally v 'tively simple pumping equiprnent for agrif cultural and horticultural service, suitable for the spraying of'fruit trees, vine s,fetc.,

also for the applicationof insecticides,

ffungioides, etc., as well as the pumping of water-fer general purposes. V I p a r 4. To supply a readily portableland eifi V cient pumping outfit for use inthe petroleum V producingindustry, suitable for pumping i-petroleum for comparatively short distances 1 ,throug'hlpipe lines, and for 'such'other surf 7 face pumping as maybe desired.

v The constructionwherebyljarnenabledto attain said objects is' clearly illustrated in r the accompanying drawings in; which E: Fig, 1 is a' side elevation ,of the rearward I p 7 I hangers,'1Fig 5-are attached each a of 95 which isra' structural steel angle, having the '-legs"f12,;12' and 13,13v respectively.

Said axle housings are 4:- V L I attached L O the trannnssion housing by V meansof cap screws 3. As shownin said) drawings, there are} twelve of I these" ap screws, but this may not he the casein all sizesiof tractors or in tractors of the same- I "power "rating manufactured V by} difi'erent manufacturers however, in any case, the number of cap screws employed and the ar-y range'ment and spacing of same are such7 5 that my pumpingequlpment may be'rea dily" adapted tobe attached thereto in substan- 'tially the manner inclicatledinfthe drawings.

of the drawings.

Said legs 12 and 13 are each provided with one or more L-shaped gaps or. slots 16 for the purpose of receiving and'engage- 1 inent with special cap screws (Fig. the construction, arrangement and office of which areas follows. As shown in idig hdho four most rearwardly positioned cap screws "originally used on the tractor for securing the axle housings to the transmisslon housin'g, are removed and specially-formed i hanger cap screws 17 are inserted in the place of the regular caps-crews thus rcmoved; said hanger cap screws differ from said originally-supplied cap screws inthe respect that the outer end thereof, in addition'to being supplied with thegusual head,

- After said hangercap screws have been supplied, the pump equipment is connected to ersuspended from said transmission hous ing by positioning said hanger legs 12". and '13 upon opposite sides of the transmission; housing then moving said pump structure "forward until the two most rearwardly posi- 35 jtioned hanger pins 18 haveenteredthe open,

' horizontally-disposed branch of the respec- Itively-adjacent slots 16, whereupon the pump structure is lowered until said rear ward pins 18 occupy the upper end of the j vertically-extending branch .of said slots '16. fIn' thispositiomthe forward edge of said legs :12 and.l3..bear upon theother two. 7 upper and lower, adjacent pins 18 and the pump isthereby securely suspended upon th'e'tractor frame, V p

Said hanger members extend'below the. base plate 10 and one leg-of a transverselyextending. cross angle is securely attached to the. lower ends of said members;..-the other b -leg i195 foffl'said cross-angle extends rearval dly andprojectsover'. thexdraw-barrlug '1". 20, i and 'isfspace'clabove the same.
